            bool b = IsAdministrator();
            if (b != true)
            {
                MessageBox.Show("You Should Login as Admininstartor to run this Software at it's fullest.");
            }
            string TargetFolder = @"C:\Users\user\AppData\Local\Temp";
            DeleteFolderAndFile(new DirectoryInfo(TargetFolder));
    }

static public void DeleteFolderFile(DirectoryInfo directoryInfo)
        { 
            try
            {
                foreach (FileInfo file in directoryInfo.GetFiles())
                {
                    try
                    {
                        file.Delete();

                        //Do Nothing
                    }
                }
                foreach (DirectoryInfo Folder in directoryInfo.GetDirectories())
                {
                    try
                    {
                        Folder.Delete(true);
                    }
                    catch
                    {
                        //Do Nothing
                    }
                }
                foreach (DirectoryInfo subfolder in directoryInfo.GetDirectories())
                {
                    try
                    {
                        DeleteFolderAndFile(subfolder);
                    }
                    catch
                    {
                        //Do Nothing
                    }
                }
            }
            catch
            { 
                //Do Nothing
            }

        }

Problem Is only Main Folder are left undeleted.

You should use the DirectoryInfo delete method with the Boolean argument of true to recursively delete. Call this once on the parent/target folder.

    DirectoryInfo dir = new DirectoryInfo(TargetFolder);

dir.Delete(true);
